Window sash supporting means



J. BELLER WINDOW SASH SUPPORTING MEANS Filed March 15, 1948 Dec. 6, 1949 INVENTOR. (7052 71 Heller BY my M9 Patented Dec. 6, 1949 iJNlTED STATES OFFICE This invention relates to window sash supporting devices and has particular relation to those supporting devices which without sash cords or weights will hold a window sash in any adjusted desired position.

The primary object of the invention is the provision of an improved window sash supporting means.

Another object of the invention is the provision of a Window sash supporting means which will have a tendency to center the sash in a position to give each side the same clearance from the sides of the window frame, thus making it easier to start raising or lowering the sash.

Another object of the invention is the provision of an improved window sash supporting means wherein oppositely disposed rolling members engage opposite sides of an elongated member in a manner to retard the tendency of the sash to move until the operator desires it to be moved.

A further object of the invention is the provision of an improved window sash supporting means wherein oppositely disposed rotative means contact a fin which may be weather-stripping and retard relative movement between the window sash and its frame while still not preventing slight movement normal to the plane of the sash, thereby tending to prevent binding of the sash in the window frame.

A still further object of the invention is the provision of an improved window sash supporting means wherein a pair of oppositely disposed rotative members are held against an elongated fin by a single spring means in such a manner as to retard the movement of the sash until movement is desired by the operator.

Another and further object of the invention is the provision of an improved window sash supporting means wherein a main body member is provided with a pair of oppositely disposed rotative members having supporting means for supporting them in the holder in such a manner that they may grip a relatively stationary fin to prevent ready movement of the sash in the frame to open or shut the window but will allow slight movement of the sash substantially in the plane of the sash and normal to the plane of the sash While still retaining the rotative members in contact with the fin.

Other and further objects of the invention will be apparent to those skilled in the art from a reading of the complete specification.

Referring to the drawing wherein the invention is illustrated:

Fig. 8 is a section view of the form of the invention illustrated in Figs. 6 and '7 and taken on the line 8-8 of Fig. '7.

Throughout the specification and drawing, the same reference characters refer to the same and similar parts.

In Fig. 1, there is illustrated a window frame it having sashes H. In the form of the invention illustrated, although not necessarily, there is illustrated a T-shaped member 12 attached to the window frame and a holder member l3 secured in the sash, as will be presently described in detail.

The T-shaped member I2 is provided with an outwardly tapered fin M, the tapered construction being for a purpose to be described.

The housing or holder member I3 is illustrated at the top and left of the upper sash of Figure 1 and in Fig. 2, shown with its axis in the plane of the window sash. It will be understood that the sides of the sash H are provided with slots is throughout their lengths for coaction with the weather stripping such as the fin l4 of the T-shaped. member H which serves as a slideway.

In the cylindrical side of the holding member it are two bearings to support the pivot member I5. On this pivot member Hi, there is journalled a rotative member l1. Integral with this rotative member I1 is a sleeve extension l8. At the end of the extension 18 is a washer or flange I9. This washer or flange l9 may be made integral with the extension is by soldering or in any other suitable manner after the parts have been assembled.

Surrounding the extension [8 and freely movable therealong is the rotative member 20. Adjacent the extension member 18 and on the rotative member 28 is a hub 2| which tends to give stability to the rotative member 20. In order tonormally have the rotative members l8 and 20 forced to ward each other, there is provided a spring member 22. This spring 22 is held in place between the washer l9 and the side of the rotative member 20 and when in full operation, tends to hold the rotative members against the tapered sides of the fin I 4.

It is to be here noted that there is a space between the extension 24 of the hub of the rotative member I and the housing member l3, and a similar space at the outer side of the washer l9. These spaces provide for a limited movement of the rotative member I! together with the rotative member and the spring member 22, along the pivot member It. This movement may take place while still permitting the rotative members I I and 20 to grip the fin M. This construction which permits this free limited movement'normal to the plane of the sash, tends to prevent the binding or sticking of the sash II in the window frame l0, yet holding the sash in the desired adjusted position. It will be noted that the adjacent sides of the rotative members I! and 20 have a wiping action on the sides of the fin l4. This action on the fin is one which gives an excellent grip on the fin and consequently holds the sash in the desired position, until it is desired to place the window at another adjustment.

It is believed obvious that when the tension of the spring 22 is increased and the window moved, there will be a tendency of the spring 22 to move the rotative members toward each other and along the sides of the fin toward the tapered edge. With these units at opposite sides of the sash, this tendency of one unit to move toward the edge of the fin is counteracted by the action of the other unit at the opposite side of the sash. The tendency of each spring 22 is to move the sash, in its plane, away from the side of the frame at which the spring 22 is located. This is because 'of the tapered cross section of the fin M. This tendency is counteracted by the action of the spring 22 at the opposite side of the sash. So that, if the sash is moved by hand, during raising or lowering, to a position farther, for example, from the left side, the spring on the right side tends to move the sash back toward the left side in the opposite direction to a condition where the two opposing springs 22 at opposite sides of the sash will be equally compressed. This, as already pointed out, is brought about by the taper of the fin I4 and the tendency of the rotative members I? and 29 to work off of the edge of the taper as-they turn, thus, each fin tending to force the -sash to the opposite side. Thus an equilibrium is obtained with the sash tending to rest at equal distances from the opposite sides of the window frame. This central placing tends to make the window easier to start either in an up or a down "direction.

"In the drawing, suitable fastening means may be provided if desired but since these are not a part of this invention, per se, they have been indicated only in dotted lines.

In Figs. 6, '7 and 8 is illustrated a modification in which ahousing member 36 is cut away and bent back to form an entry 3| for the fin l 4. The pivot member 32'is secured in the opposite walls of the housing member 30. Mounted loosely on the pivot member 32 are apair of complementary members 34 and 35 which are similarly con- -structed5the forward-ends of the members 34 and 35 being provided with openings in which are secured loosely 'therotative members 36, which are spherical in shapeandLmay be ball-bearings. For this purpose the outer ends of the members34 and 35 are provided with oppositely disposed depressions 3'! for the purpose of seating the balls 36. The openings through which passes the pivot member 32 are designated at 39 and are sufficiently large to permit of considerable movement of the members 34 and 35 on the pivot member 32.

The depressions 38 in the inner ends of the members 34 and 35 accommodate the spring member 39' which tends to push the outer ends of the members 34 and 35 apart. This action, due to the angularity of the members 34 and 35, tends to force the outer ends carrying the ball 36 towards each other. When in position to function with the din 1:4 between the spherical members 31, the spring 39 will force the members against the-fin 14. Due to the angularity of the members 34 and 35,the action of the members 34 and 35 on the fin I4 is similar to the action of the members I 1 and'2ll heretofore described.

The limited movement in a direction normal to the plane of IthG SEShiSItZKEH care of by the openings 39 being larger :than'the pivot member 32. The centering action of the unit is due to the coactionrof the spherical members 3'! with the tapered sides of the fin M in a manner similar to the action .betweenthe rotative members l1 and 20 with the taperedzsides of the fin [2a, as already described.

In Figs. 6 and 7,1 :have indicated by dotted lines the position of securing lugs 40 which may be added if desired. Since'these securing means are nota'part of this'invention per se, they will not be further described.

While I have shown and described my invention in detail, it is to beunderstood that the disclosure is merely illustrative and that modifications and changes maybe made without departing from the spirit of 'the invention and within its scope as claimed.
